The cobalt(II) complex [Co(C5H5NCH2CO2)2(NCS)(H2O)3]2 [Co(NCS)4] has been synthesized, and characterized by X-ray crystallography. The complex comprises distorted octahedral [CO(C5H5NCH2CO2)2(NCS)(H2O)3]+ cations, in which the cobalt atom is surrounded by two trans monodentate pyridine betaine ligands, one N-bonded thiocyanate ligand and three aqua ligands, as well as distorted tetrahedral [CO(NCS)4]2- anions. Two-thirds of the aqua ligands form intra- and inter-molecular hydrogen bonds with the coordinated and uncoordinated carboxylate oxygens , linking the cations into a one-dimensional polymeric block directed along a 21 axis.
